Yokohama (横浜市 Yokohama-shi) ( listen (help·info)) is the capital city of Kanagawa Prefecture and the second largest city in Japan by population after Tokyo and most populous municipality of Japan. It lies on Tokyo Bay, south of Tokyo, in the Kantō region of the main island of Honshu. It is a major commercial hub of the Greater Tokyo Area.
Yokohama's population of 3.7 million makes it Japan's largest incorporated city. Yokohama had been the world's largest suburb until the formation of New Taipei (excluding Mainland China as cities there are nonstandard).
Yokohama developed rapidly as Japan's prominent port city following the end of Japan's relative isolation in the mid-19th century, and is today one of its major ports along with Kobe, Osaka, Nagoya, Hakata, Tokyo, and Chiba.
The Port of Yokohama (横浜港 Yokohama-kō) is operated by the Port and Harbor Bureau of the City of Yokohama in Japan. It opens onto Tokyo Bay. The port is located at a latitude of 35.27.–00°N and a longitude of 139.38–46°E. To the south lies the Port of Yokosuka; to the north, the ports of Kawasaki and Tokyo.
